Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449508, here are decompositions:

29 + 31449479 = 31449508
59 + 31449449 = 31449508
107 + 31449401 = 31449508
131 + 31449377 = 31449508
149 + 31449359 = 31449508
317 + 31449191 = 31449508
479 + 31449029 = 31449508
491 + 31449017 = 31449508

Showing the first eight; more decompositions exist.
